{BENCH-PLANE.

SPECIFICATION forming part of Letters Patent No. 455,957, dated July 14,1891. Application'led March 7. 1891. Serial No. 384,110. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES F. YOUNG, a citizen of the United States,residing at Birmingham, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Bench-Planes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin ro the art to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements inbench-planes.

It is the object of my invention to improve r 5 upon the construction ofplane commonly known as the Bailey plane, and which is shown anddescribed in 'Letters Patent No. 67,398, dated August G, 1367, in suchmanner that while the bit may be freely fed and adj usted longitudinallyin the seat in substantially the manner indicated in said patent toBailey said bit may also be adjusted laterally for the purpose ofsquaring its edge with the plane-mouth; and with these ends in view myinvention consists in the construction and combination of elementsherein shown and described, and then. recited in the claims, and in themeans for effecting the side adjustment of the bit, and particularly inmounting the ad- 3o justing-lever and its connections upon a movableblock which is pivoted or otherwise suitably attached beneath the frog.

In order that those skilled in the art to which my invention appertainsmay fully un- 3 5 derstand its construction and operation, I willdescribe the same in detail, reference vbeing had to the accompanyingdrawings and the numerals markedthereon, which form a part of thisspecification, and in which- Figure lis a central longitudinal sectionof a plane constructed in accordance with my invention; Fig. 2, a planView of the upper surface of the frog, the bit and cap-plate beingremoved; and Fig. 3, a rear view showing` the frog and the swingingblock, the adjusting-lever and its screw being removed.

The body and sole of the plane 1 are of any usual or ordinaryconstruction, and 2 is a xed frog, whose upper end is slotted, as

shown at 3, Fig. 2, and against whose face the 5o under side ot the bitl is adapted to rest.

' 5 is a cap-plate of ordinary construction superposed upon the bit andsecured thereto by a screw 6, as is com mou and usual, and 7 is aclamping-wedge which binds the bit against the frog by engagement withthe screw S. All of the foregoing' is old and well known in the art ofplane-making.

9 is a block, whose sectional shape is shown at Fig. 1 and whose outlineappears at Fig. 3. Said block is pivotally secured'to the frog by ascrew or rivet 10, which passes through the upper end of said block andenters the frog, as is clearly shown at Fig. 1. Near its center saidblock has an opening 1l, which when in 65 assembled position registerswith the opening 3 in the frog, and upon either side of said opening arelugs or cheeks 12. Between these cheeks is extended a pin 13, upon whicha lever 14 is fulcrumed. The rear end of this 7o lever is yoked, and thearms of the yoke engage an annular groove in a thumb-nut 15, whichlatter runs upon a screw 16, set in and projecting rearwardly from thethick lower portion of the block 9. By means of this leverand-screwarrangement the longitudinal movement of the bit is effected, the noseof the lever 14 engaging' either with a slot in the cap-iron, or, asshown in Fig. 1, in a slot cut in a small rectangular piece of metal1'7, 8o laid in the longitudinal slot of the bit and held in position bymeans of the screw G.

13 is a screw letinto the rearof thefrog in such manner that its headslightly overlaps the outer end of the block 9, so as to afford somesupport to said block, but not to interfere with the sidewise movementof the latter about its pivot.

In the operation of my invention the longitudinal movement of the bitmay be freely 9o accomplished through the nut 15 operating the lever 14about its fulcrum, after the manner of the well-known Bailey plane,heretofore referred to. When it is desired to laterally adjust the bit,the block 9 may be swung 95 sidewise upon its pivot beneath the frog,whereupon the engagement of the nose of the lever with the bed or capplate will move the latter, Operating thereon after the manner of alever of `the second order. As the lever and sc rew 14 16 are secured tothe block and move with it, their operation is in no way aiiected by themovement of the block.

In this invention I am able to dispense with the levers, which haveheretofore been formed independently and in some Way connected to thebit, while at the same time I secure a very simple adjusting devicewhich is economical to manufacture and from its position beneath thefrog is neither liable to be injured nor its adjustment changedaccidentally-as, for instance, by a fall of the plane. The rear edges ofthe block 19, as shown at Fig. 3, project sufficiently to admit of theready operation of the block by the thumb or inger applied thereto.

l. In a bench-plane, the combination, with the frog and the bit securedthereon, of a 'block pivoted beneath the frog and adapted to have aswinging movement relative thereto, an adjusting-lever fulcrumed in saidblock and having operative engagement with the bit, and adjustingdevices carried by said to the adjusting-lever, substantially asdescribed.

3. In a bench-plane, the combinatiomwith the bit and frog, of the block9, pivoted to the frog, as at 10, the lever 14, having operativeengagement with the bit, and the screw device 15 16, whereby saidleveris moved about its fulerum, said block and lever adapted to be movelaterally for the side adjustment of the bitabout the pivot 10,substantially as described.

In testimony whereof I affix my signature ir presence of two witnesses.
